Rooflights for flat roofs: Hard shell, insulated core
Let in sunshine and moonlight, but keep out heat and cold: alwitra skylight domes are available in single, double, triple and multi-skin versions and have different thermal insulation properties. They also ensure good light diffusion with low light loss. Reassuring: the standard, burglar-delaying screw system makes life extra difficult for thieves.
